Abstract: To ensure normal operation of an internal combustion engine, it is necessary to select a cooling system that maintains optimal temperatures in the combustion chamber, cylinder head, cylinder walls, and piston surfaces at levels close to their maximum permissible values. The coolant parameters characterize the physicochemical and thermophysical properties of the heat-transfer medium within the cooling system. Reliable engine operation can be ensured if the cooling agent meets the following requirements: it must not cause surface corrosion and must remain stable over an extended period. These properties can be achieved through the appropriate chemical composition of the heat transfer medium and special treatment. The article considers the influence of water-chemical parameters in a marine engine cooling system on the reliability of engine operation when various chemical additives are used.
